Implementation research

• Implementation research is the scientific study of methods to promote the systematic uptake of research findings and other evidence-based practices into routine practice, and, hence, to improve the quality and effectiveness of health services and public health

• It includes the study of influences on healthcare professional and organizational behaviour.
